38 Striker Clip Position

[Ndog]

I know it depends on temperature, humidity, altitude, pipe, and porting but I just am curious where most of you with the 38mm striker are running your clip at on your needle. I know that 2 strokes tend to run rich in the middle by nature. Here is my specs:

Indiana (700ft above sea level)
80-90 degrees right now
50-60 percent humidity
wiseco pro- lite (66.75mm)
port and polished
ESR full exhaust system
ESR reedblock with spacer
uni filter with airbox lid off
170 main 38 pilot

Normally, I would just change and ride but my carb is barely crammed in the intake and the airboot is touchy so it is hard to turn it and access the slide. Im trying to avoid doing it twice.
The clip is currently in the middle and its rich. Should I drop the needle all the way down or just one notch leaner?

Thanks again

I have mine 1 notch above middle in summer, If its that big of a hassle, you might just leave it where its at because in another month or so you'll be puting it right back.

it all depends on what needle you have.It should be stampped near the top of the needle(ex: dgh, dgj, etc) by the looks of your mods, i think you are lean on your pilot and main jet. did you buy the carb from esr?. i am running all of the same bolt on parts with esr trx9 porting and im running a 48 pilot and 178 main, which may be a little on the rich side too. mine isnt completely dialed in either. i would reccommend finding out what needle you have and then give ESR a call

I have all the same settings as you. When I recieved my AS 38 carb I raised the clip one to lower the needle. I also have a 170 main. My bike rips. I would try the clip, or see if they have a 168

I have the stock needle that the CR250's get. Looks like ill just drop the needle one notch. I run a 38 pilot in my 2000 cr250 too. Everything comes with such a big pilot. You are rarely at below a 1/4 throttle and crisping the pilot helps your response a ton. For almost anywhere I could not imagine running a pilot higher than 42 except in the winter.

Thanks for the help guys

I can't imagine running anything less then a 48 lol...I have to admit,Its taken me almost a year to get my bike to where its at now.. As far as my pos 38 a/s goes lol...Im running a 175 main 52 pilot,Stock needle that came with the carb @ middle clip..My trike pulls power wheelies in 5th with ease and im running stock gearing..Im pretty sure i could do it 6th just haven't really tried...So yeah my R is running real good right now...Can't complain about anything to this point

Well, we all live in different area of the country at different altitudes. I run a 42 pilot on my 2000 CR250 and could probably go with a 38. Right now in Indiana is is just so sticky and humid that everything runs rich as heck. I had to adjust my lawn tractor.LOL! Also, different people have different goals in jetting. Me, i am not satisfied with a normal jet where you are just like "runs good". I go for a very light tan dry plug and crispy response. I want max power. For trail riding and stuff a larger pilot is probably good. The difference between jetting that runs good and jetting for max power can be 2 sizes different. I dont go lean to the point where my power fades though. Also, race gas makes a bike run richer so there could be some issues there as well as bore size. Even a piston oversized slightly (like mine is 66.75) compared to a stock 66 will affect jetting. Larger bore makes makes more intake velocity so you actually have to lower jetting. This is most noticed at idle.
